GAGE-GLASS.

170 all whom it may concern:

.Be it known 'that I, CHARLES L. DromensoN, a citizen of the United States,'residing at Clinton, in the county of .Dewitt and State' Another object of this invention is the pro duction of a gage-glass, which will allow the height of the liquid-to be determined from one side of the saine thereby obviating the necessity of viewing the glass from both sides order to determine the actual height of the liquid therein.

A further object of this invention is the production of a gage-glass, which will allow the removal of the glass for cleaning and polishing thesame when the same has become frosted in appearance, as often vhappens in the ordinary gage-glass now in use.

With these and other objects in view this invention consists of` certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.

1n the drawings: Figure 1 is a side view A two of the saine in section; Fig. 2 is a frontl view of the same; Fig. 3 is a section taken on. line 3-3 of Fig. 1; Fig. 4 is a fragmentaryview of the upper connection of the valve to, the gage-glass.

Referring to the drawings by numerals, 1

` designates the upper valve and 2 the lower valve, which are adapted to be secured to the boiler or other receptacle. To the lower valve 2 is secured an additionalvalve 3 for allowing the gage-glass to be; drained of its contents after the valves 1 and 2 have been closed. v

The gage-glass proper comprises a plurality of barrel-portions 4, which are positioned in zigzag relation,- relative to .the vertical axis of the gage, so as to have the top of one barrel on the level with; the bottom of the other-barrel, positioned above the lastto gage-glasses, and

mentioned barrel-portion, as shown in Fig. 1 and 'indicated by the line :z2-w. It will be obvious that when the liquid in the barrel-portions 4 rises'to such an extent as to overflow one barrel-portion that as soon as the liquid has reached the top of said barrel-'portion the liquid will immediately begin to iiow in the barrel-portion positioned directly above the last-mentioned barrel-pon tion, as is clearly shown in Fig. 1. The barrel-portions 4 are integrally connected and are provided with a communicating passagev way 5, which allows the liquid to readily ilow from one barrel-portion to the other, thereby allowing the level of the liquid to be -readily determined, when viewing the gage from one side.

The barrel-portions 4 are connected to the valves 1 and 2 by means of communicating -pipe 6, which 1s screw-threaded into the eX- tremital barrel-portions, as shown in Fig. 1,

and in detail in Fig. 4. The communicating pipe 6 is provided, at one end, with a flanged portion 7 which overhangs the ilaiige 8 of the nut 9, and is firmly held in engage ment with the valve portion 1. The nut-9 is threaded upon the lower portion of the valve portion 1 and the washer 10 is positioned intermediate the valve portions and the flanged portion Tof the communicating pipe 6, thereby forming a tight joint.

The barrel-portions 4 comprise a cylindrical hollow body portion 11, which are provided with socketed outer ends 12, `which outer endsy are screw-threaded, as at 13. A. packing ring or gasket 14 is positioned upon the inner end of the socket portion 12 and a. glass 15 is positioned against said gasket 14, and an additional gasket 16 is positioned against the outer edge of the glass 15. .A nut 17 is threaded into the screw-threadedend of the tubular body portion 11 and en- .gages, at its inner end, the gasket 16, thereby rmly clamping the glass 15 within the sockets. It ywill be obvious that any pressure upon the inside of the glass will not break or crack the same for the glass will bear against the yieldable packing ring or asketl 16. However, the nut 17 is threaded into the threaded end of the' tubular body portion 11 of the barrel-portion 4 and rmly clamps the glass in the sockets 12.

From the' foregoing description, it will be readily seen that I have provided an improved gage-glass, which will allow the level of the liquid in the receptacle to which the glass is attached to be readily determined by viewing the same from one side, and I h. ve i also provided a glass, Which can be read ly i repaired, if any part thereof is broken, Without removing the ent-ire gage and replacing a neW one therefor.

It Willalso be obvious, as stated above, that by having the tubular portions arranged as clearly shown in section in Fig. 1 that the liquid will, as soon as one of the barrel-portions is overflowed, flow into the 'barrel-por-l tion next above said last-mentioned barrel-I y portion, vthrough the ports or openings 5.

What I claim is:

1. A gage of the class described compris-- ing a plurality of barrel-portions positioned zigzag With respect to the gage, and arranged so that the top of thefg inner ortion of one barrel Will be on ,the level With the bottom of the barrel just above the vertical anis of 2. A gage of the class described comprising a plurality of barrel-portions positionedl in a staggered relation in reference to the Vertical axis of the same. i

3. A gage of the class ldescribed comprising a plurality of hollovs7` barrel portions, transparent means positioned in each end of said barrel-portions, said barrel-portions p0- sitiohed in staggered relation and having the top of the inner bore of one barrelportion on a level with the bottom of the inner bore of the other barrel-portion for readily allovv ing the liquid containecltherein to be viewed from either side thereof.

In testimony whereot` I hereunto affix my l signature in presence of two Witnesses.
